Abstract: In one example, a method includes selectively activating, by control logic and based on a control signal, a switch; in response to determining that an electrical characteristic of a signal provided to the switch satisfies a threshold while the switch is deactivated, activating, by the control logic and regardless of the control signal, the switch until determining that a potential of the signal provided to the switch satisfies a threshold potential; and in response to determining that the potential of the signal provided to the switch satisfies the threshold potential, deactivating the switch.

Abstract: A semiconductor device, overvoltage detection structure is described that includes a current path including a Zener diode connected in series with a fuse. The Zener diode is configured to conduct a current in response to an overvoltage condition at a semiconductor device and the fuse is configured to permanently break the current path of the overvoltage detection structure in response to the Zener diode conducting the current.

Abstract: A circuit configuration for protecting a MOSFET against overvoltages, includes at least one diode connected in the blocking direction between a drain terminal and a gate terminal of the MOSFET to be protected. A series connection of a load path of a further MOSFET and a further Zener diode connected in the blocking direction, is connected between the at least one Zener diode and the gate terminal of the MOSFET to be protected. A cathode of the further Zener diode is connected to a gate terminal of the further MOSFET.

Abstract: A differential amplifier includes two differential amplifier stages each having an input side with two complementary inputs and an output side with at least one output. The stages are connected parallel to one another on the input and output sides. The stages each include a source-coupled transistor pair. One of the transistor pairs has two depletion MOS field effect transistors of a given conduction type and the other of the transistor pairs has two enhancement MOS field effect transistors of the given conduction type. Current sources each supply a respective one of the transistor pairs.

Abstract: An analog/digital converter operating on the principle of charge distribution includes a capacitor network having dual-weighted capacitors including two smallest capacitors. The capacitors each have two terminals. A comparator has a first input connected to one of the terminals of each of the capacitors and a second input and a reference switch is connected between each of the one terminals and a first reference potential. Other switches each selectively connect the other of the terminals of a respective one of the capacitors to an input analog potential, the first reference potential and a second reference potential. A coupling capacitor is connected upstream of the first input of the comparator.
